  • the heat contained in the exhaust gas can be converted into electrical energy.
  • heat exchangers of the type mentioned are used, which comprise at least one thermoelectric generator having a hot side and a cold side.
  • heat exchangers can be used to transfer the heat from the exhaust gas, which then serves as a heating medium in a coolant, for example. In order to heat a passenger compartment or the coolant, then is used as a tool to vaporize within a Rankine cycle process.
  • a heat exchanger having at least one thermoelectric generator further comprises at least one heating tube for guiding a heating means, which is arranged on at least one hot side of such a thermoelectric generator, and at least one cooling tube for guiding a coolant, which at least one cold side of such a thermoelectric Generator is arranged.
  • the at least one thermoelectric generator, the at least one heating tube and the at least one cooling tube in a Stacking direction are stacked on each other and thus form a stack of tubes in which extend the respective thermoelectric generator, the respective heating tube and the respective cooling tube parallel to each other in a longitudinal direction of the tube stack.
  • EP 2 378 578 describes a heat exchanger for an exhaust system.
  • the present invention addresses the problem of providing for such a heat exchanger, which contains at least one thermoelectric generator, an improved or at least another embodiment, which is characterized in particular by an increased energy efficiency. At the same time a simple and thus inexpensive construction is sought.
  • the invention is based on the general idea to equip the heat exchanger with a housing which receives the tube stack in an inner space and which has a jacket which encloses the tube stack in a circumferential direction.
  • the circumferential direction refers to the longitudinal direction of the tubes or the tube stack.
  • the invention is based on the general idea to design the housing or the shell as a biasing spring, which compresses the tube stack in the stacking direction, thereby improving the heat-transferring contact between the individual components of the tube stack. It has been found that applying the stacked components in the stack of tubes, ie the heating tubes, the cooling tubes and the thermoelectric generators leads to improved heat transfer, which improves the energy efficiency of the heat exchanger. By integrating the biasing function in the housing or in the jacket can on additional separate components, such as

  • the relaxed state is in the absence of tube stack.
  • the tensioned state is present at least when the heat exchanger is fully assembled.
  • the cocked condition can be adjusted in advance, e.g. when the tube stack is inserted into the housing and the housing or the jacket is completely assembled. For this purpose, it may be necessary, for example, to close the housing or the casing at least in an axial section at least in the circumferential direction.
  • the integration of the respective biasing portion in the shell means that no additional separate component is required to produce the required biasing force, which must be mounted on the shell, since the biasing portion that generates the desired biasing force forms an integral part of the shell, so by one corresponding portion or portion of the shell is formed.
  • the respective biasing portion is thus an integral part of the housing, so no related component in this respect.
  • the biasing force generated by the respective biasing portion acts in parallel with the stacking direction, which in turn is perpendicular to the longitudinal direction of the plate stack, there is an uneven force distribution in the circumferential direction.
  • the respective prestressing section can have no or only greatly reduced prestressing forces transverse to it produce.
  • the respective biasing portion extends in cross-section perpendicular to the longitudinal central axis of the plate stack in the circumferential direction over an angular range of less than 180 °, for example about 90 ° or less.

In the cross-section of the plate stack, these two sides then run essentially transversely to the stacking direction, while the two other sides then run essentially parallel to the stacking direction.
  • the jacket in the region of the respective biasing portion may be designed so that the housing has an inner cross-sectional area in the absence of tube stack, ie in the relaxed state, transverse to the longitudinal direction of the housing, which is coincident with the longitudinal direction of the tube stack, which is smaller than an inner cross-sectional area, which has the housing when the tube stack is inserted therein and the tensioned state is present.

  • the tube stack is then inserted axially into the casing, so that the above-mentioned widening of the inner cross-section results when the tube stack is inserted into the casing.
  • the housing can also be formed from two half-shells, which are fastened to one another in the region of a parting plane at the ends facing each other, bpsw. by means of welded connections or crimp connections.
  • the tube stack is first inserted into the one half of the housing. Following this, the other housing half is placed, wherein for closing the housing in the circumferential direction, ie for fixing the two housing halves together, the housing must be elastically deformed in the respective biasing section to close the housing can.
  • the jacket may have at least two such integrated bias sections, which are opposite with respect to the stacking direction.

  • the flat contact area can be used to homogenize the surface pressure on the affected outer sides of the tube stack. If the housing consists of two half-shells, the parting plane expediently extends through the two wall sections extending along the stacking direction. Alternatively, it is also possible to rearrange the parting plane, e.g. through the contact area.
